and its competitive position; ExOne’s ability to enhance its current
three-dimensional (“3D”) printing machines and technology and develop
new 3D printing machines; the Company’s ability to qualify more
industrial materials in which it can print; demand for ExOne’s products;
the availability of skilled personnel; the impact of loss of key
management; the impact of market conditions and other factors on the
carrying value of long-lived assets; the Company’s ability to continue
as a going concern; the impact of customer specific terms in machine
sale agreements on the period in which the Company recognizes revenue;
risks related to global operations including effects of foreign
currency; the adequacy of sources of liquidity; the amount and
sufficiency of funds for required capital expenditures, working capital,
and debt service; dependency on certain critical suppliers; nature or

maintenance expenses, insurance expenses and deductibles, interest
expenses, debt levels, and other matters with regard to outlook.
